Accept viewNames and excludedViewNames for ThymeleafViewResolver

(via spring.thymeleaf.*).

Fixes gh-548
Allow user to opt out of ContentNegotiatingViewResolver

The bean ID for the ContentNegotiatingViewResolver is now
"viewResolver" (it is the *one*). The conditions have been changed
so that a user only has to define a bean of the same name to switch
it off.

Fixes gh-546
minor doc changes based on RC5 migration experience
Fix issue with paralellism and CodaHale metrics

Since there is no atomic remove/register operation for
Gauges, we need to synchronize.
Tweak to support finer grained locking

Fixes gh-543
Add marker interface for non-embedded servlet container

ErrorPageFilter is itself an EmbeddedServletContainerFactory
but it runs in a non-embedded container. Any component that assumes
the presence of an EmbeddedServletContainerFactory implies we are
running embedded is therefore invalid. WebSocketAutoConfiguration
had that problem.

Fixes gh-551
Prevent accidental failure of deployed war when management.port is set

We can't support (yet) embedded containers inside a deployed war (class
loader conflicts are inevitable, really). Until we figure out a way to
do it, we should just log a warning and advise the user to switch to
JMX for the actuator endpoints.

See gh-552
Use reflection to setup Websocket SCI so it works in Tomcat 8

Annoyingly this is necessary if we want to support Tomcat 7 and 8
since the package name changed.

Fixes gh-554
Add README to starters

Basic README content plus a short table of community-
contributed additional starters.

See gh-539
Correct property path for management.address

Fixes gh-558
Pass custom ResourceLoader down to read config files

If user sets a ResourceLoader on the SpringApplication, he might
reasonably expect that it would be used to read the config files.
This change ensures that it is (instead of just using the
DefaultResourceLoader).
Allow Batch configuration without DataSource

If the user provides a JobExplorer and a BatchConfigurer that
don't require a DataSource we can back off on configuring ours
(and anything else that needs a DataSource).

Fixes gh-561
Prevent retention of child from parent

When the child is listening for parent closed events
the parent has a reference to the listener which contains the chils.
Thust there is a cycle of references and a GC probalem waiting to
happen.

This change breaks the cycle by making the reference to the
child a WeakReference.

Fixes gh-559
Polish ParentContextCloserApplicationListener

Fix formatting for the recent ParentContextCloserApplicationListener
change, also some minor internal renames.
Link to community contributed starters README

Update reference docs to link to the community starters README.
Rename @ConfigurationProperties attributes

Rename `name` to `prefix` and `path` to `locations`.
Security Documentation Cleanup

- Add link to Spring Security's Global Method Security Java Configuration
- Fix link to SecurityProperties
- Add link to SECURITY Common application properties
- Remove unnecessary @Order from SecurityConfiguration
- Change method signature for @Autowired AuthenticationManagerBuilder to
  compile / match Spring docs
Escape URL characters in JAR URLs

Update the spring-boot-loader JarURLConnection class to decode entry
names in the same way as the stock JDK class. This allows encoded
entry names in the form `%c3%ab` to be loaded.
